\([{2}/{(2\pi )^3}]\int _0^{\infty }n^J_{\mathbf {k}}(\rho ,\delta )\mathrm {d}\mathbf {k}=\rho _J=(k_{\mathrm {F}}^{J})^3/3\pi ^2\) .
Only two of the three parameters \(\Delta _J\) , \(C_J\)  and
\(\phi _J\)  are independent. Using the last two as independent parameters and assuming they have the same isospin dependence, i.e,
\(Y_J=Y_0(1+Y_1\tau _3^J\delta )\)  with \(Y=C\)  or \(\phi \)  [1]}, the associated parameters were correspondingly constrained to be about \(C_0\approx 0.161\pm 0.015,C_1\approx -0.25\pm 0.07,\phi _0\approx 2.38\pm 0.56\)  and \(\phi _1\approx -0.56\pm 0.10\)  using information from the SRC experiments [2]}, [3]}, see, e.g., Ref. [4]} for a recent review on related issues [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}.
